Twelve years after its establishment, Vogt set up production with John Harwood, inventor of the automatic wristwatch.

In 1937, Fortis commemorated the company's 25th anniversary by manufacturing and marketing its first chronographs, including the Rolls and the Autorist.

This same year the Star City Training Center chose the Fortis Official Cosmonauts Chronograph as part of its issued equipment.

In 2004, the Flieger Chronograph was awarded the inaugural trophy of the European Aviation Watch of the Year.
